They'll have their own kind of normal. Those two are too adventuresome and too full of energy and skills to just fade in the background. That's my head canon for them.

Oh of course. My fiance and I are not quite that normal either. The thought of buying a house and settling down is disgusting to both of us. I mean, we're both boring introverts, but there is a certain amount of distaste about the whole idea of doing what society thinks married couples should do.

In the same vein, it'll be the first time that Bruce is functioning without being driven by pain, and it'll be the first time that Selina is functioning without being driven by desperation. So that's their new adventure - getting a handle on all that baggage and being optimistic about it.
